Utilize %pe format specifier from vsprintf while printing error logs
with dev_err(). Discards the use of unnecessary explicit casting and
prints symbolic error name which might prove to be convenient during
debugging.

Changes in v2:
  - Rewrite commit subject line outlining the usage of %pe.
  - Add a separator between regmap and its error name.

Based on conversations in [1] & [2].

Side note on this one.  Would have made sense to combine the two patches
for the bmg160 gyro into one, but doesn't really matter.

Applied.

Thanks,
